Jason Alexander Pays Tribute To His 'Seinfeld' TV Mom Estelle Harris

Actor Jason Alexander is paying tribute to the late Estelle Harris, who recently passed away at the age of 93.

The actress, who was probably best known for playing George Costanza’s (Jason Alexander) mother Estelle Costanza on NBC’s sitcom “Seinfeld,” passed away on Saturday night of natural causes in Palm Desert, California, just two days shy of her 94th birthday on April 4.

She had been born on April 4, 1928. Her son, Glen Harris told Deadline, “It is with the greatest remorse and sadness to announce that Estelle Harris has passed on this evening at 6:25 pm. Her kindness, passion, sensitivity, humor, empathy, and love were practically unrivaled, and she will be terribly missed by all those who knew her.”

Shortly after her passing, Alexander took to Twitter to pay his respects to his late TV mother.

On April 3, shortly after her death was announced, Jason Alexander tweeted, “One of my favorite people has passed - my tv mama, Estelle Harris. The joy of playing with her and relishing her glorious laughter was a treat. I adore you, Estelle. Love to your family. Serenity now and always. #RIPEstelleHarris”

Harris appeared as Mrs. Costanza on 27 episodes of “Seinfeld” from 1992 to 1998. She first appeared in “The Contest” when she ends up in the hospital after she walks in on George losing the contest.

And here’s a fun fact for “Seinfeld” fans: the character was named Estelle even before Harris landed the part. Some things were simply meant to be!

Many fans piled on the post to express their condolences as well.

“#RIPEstelleHarris You two had magnificent chemistry,” one fan commented. “The scene where she was in the hospital and you were "somewhat" distracted by the woman getting a sponge bath behind the curtain was gold. I laugh everytime I watch it like it's the first time. RIP Estelle.”

“The 3 of you together were comedy perfection,” another fan commented. “Thank you for the laughter. RIP Estelle Harris.”

“Just was watching old Seinfelds on the hospital room tv last night while taking care of our newborn boy, and was just thinking how incredible she was,” another shared. “Rest In Peace, Estelle.”

Spencer Garrett commented, “So sorry for your loss, my friend. She was a gem of an actor and a beautiful person. May her memory be a blessing.”

David Becker commented, “Condolences Jason and thanks for the thousands of hours of enjoyment over the years. I will never have any problem finding a way to remember Estelle and Jerry.”

“She was such a great character actress,” wrote Ariaa Jaeger. So sorry for your loss. May her memory be a blessing.”

Dave Williams commented, “What a treat it must have been for you to work with Estelle & Jerry as your tv parents. #RIPEstelleHarris”

“My deepest condolences to the family of #RIPEstelleHarris & to ALL the directors, actors & actresses who ever had the privilege of working w/ her,” another fan commented. “She was amazing in the roles she played. But as 'Estelle Costanza' on Seinfeld....WOW!! So many laughs & tears of joy!! What a gift.”

“So sorry for your loss. She was a great lady,” another wrote. “Seinfeld is one of my favorite shows and whenever there’s a scene with George’s parents, hilarity ensues. You guys really made it seem like it was just a documentary. May she rest in peace.”

“What a treasure, and what an awesome part of comedic popular culture she and Jerry Stiller were,” another added. “Growing up, we often referred to my grandparents as the Costanzas because they reminded us so much of your on-screen parents.”
